脉冲微分方程:周期解的存在性和稳定性

Differential equations with pulses: existence and stability of periodic solutions

Alexandre A. P. Rodrigues

摘要:

我们考虑一般微分方程在$\mathbb{R}$与有限数量的双曲平衡,这是受$ω$ -周期性瞬时扰动脉冲($ω>0$)。利用原系统(无扰动)的时间- $ ω$映射,我们能够找到扰动系统的所有周期解,并研究它们的稳定性。本文建立了一个寻找$ω$的算法,研究了脉冲频率为$ω$的脉冲系统的周期解,并研究了其稳定性和鞍结分岔的位置。用我们的方法,我们能够完全地描述所考虑的系统的渐近动力学。

英文摘要:

We consider generic differential equations in $\mathbb{R}$ with a finite number of hyperbolic equilibria, which are subject to $ω$--periodic instantaneous perturbative pulses ($ω>0$). Using the time-$ ω$ map of the original system (without perturbation), we are able to find all periodic solutions of the perturbed system and study their stability. In this article, we establish an algorithm to locate $ω$--periodic solutions of impulsive systems of frequency $ω$, to study their stability and to locate Saddle-node bifurcations. With our technique, we are able to fully characterise the asymptotic dynamics of the system under consideration.
